Recent changes in Antarctic seabird populations may reflect direct and indirect responses to regional climate change. The best long-term data for high-latitude Antarctic seabirds (Adelie and Emperor penguins and snow […]
1. The rich zooplankton, fish and squid resources on the Patagonian Shelf sustain substantial populations of largely resident seabirds and marine mammals, These habitats are also visited seasonally by similar […]
Oxygen and carbon isotopic ratios were measured on left-coiling Neogloboquadrina pachyderma separated from sediments recovered from Holes 1096B (3152 m water depth) and 1101A (3280 m water depth) during Ocean […]
Echinoderms and in particular brittle stars display a remarkable ability to regenerate lost or damaged tissues. They offer an excellent model in which to study regeneration displaying extensive regenerative ability […]
Quantitative climate reconstructions are fundamental to understand long-term trends in natural climate variability and to test climate models used to predict future climate change. Recent advances in molecular geochemistry have […]
The accumulation, isotopic and chemical signals of an ice core from James Ross Island, Antarctica, are investigated for the interval from 1967 to 2008. Over this interval, comparison with station, […]
Precise relative sea level (RSL) data are important for inferring regional ice sheet histories, as well as helping to validate numerical models of ice sheet evolution and glacial isostatic adjustment. […]
